I've mentioned the German TV show “Wetten, dass..?” here, here and here. I first learned about it in this Chessbase column, which talks about Xaver Neuhausler's appearance on the show, where he performed the Knight's Tour blindfolded.

It took a little digging, but I finally managed to find video of Xaver Neuhausler's Knight's Tour footage. The fact that he's only 9 makes this feat all the more impressive.

In the Knight's Tour, the challenge is to use the Knight's L-shaped moves to land on each square of an 8 by 8 chessboard once. If you want an idea of how challenging this can be, even when you're not blindfolded, you can try it for yourself at the Grey Matters Mental Gym. You can also learn the Knight's Tour strategy there, as well.
